OK, my msg was mostly if not all off-topic but I was not aware of it. Sorry
for that. I will also answer myself as it might be useful for another lost
soul as myself. Hope you don't mind.

Look here http://www.mingw.org/ for mingw (an alternative to port code to
windows using gcc and other GNU tools)

Look here
http://www.xraylith.wisc.edu/~khan/software/gnu-win32/mno-cygwin-howto.txt
for a HOWTO on -mno-cygwin

There is a nice (easy reading and short) tutorial on the development tools
here:

http://webclub.kcom.ne.jp/ma/colinp/win32/tools/index.html

There's also documentation for RedHat GNUPro here:

http://www.redhat.com/docs/manuals/gnupro/

I don't know yet if it answers all of these questions but I would guess so.
The FAQ and User Guide are not helpfull here (unless I overlooked it).

There is also a book online on Autotools including a chapter on Cygwin here:

I still would appreciate help on this one...

Look here http://www.gimp.org/~tml/gimp/win32/ for info on the port of glib.
Don't know the answer yet.
